qjackctl: A simple Qt application to control the JACK sound server daemon1

Qjackctl is a simple Qt application to control the JACK sound server
daemon, specifically for the Linux Audio Desktop infrastructure. It is
written in C++ around the Qt3 toolkit for X11, most exclusively using Qt
Designer. It provides a simple GUI dialog for setting several JACK
daemon parameters, which are properly saved between sessions, and a way
to control of the status of the audio server daemon. With time, this
primordial interface has become richer by including an enhanced patchbay
and connection control features.
